Genes affected

SLC26A4 (HGNC:8818): (solute carrier family 26 member 4) Mutations in this gene are associated with Pendred syndrome, the most common form of syndromic deafness, an autosomal-recessive disease. It is highly homologous to the SLC26A3 gene; they have similar genomic structures and this gene is located 3' of the SLC26A3 gene. The encoded protein has homology to sulfate transporters.

Variant classified as Uncertain Significance - Favor Benign. The Ala352Thr varia nt in SLC26A4 has not been reported in the literature nor previously identified by our laboratory. Computational analyses (biochemical amino acid properties, co nservation, PolyPhen2, SIFT, AlignGVGD) do not suggest a high likelihood of impa ct to the protein. However, this information is not predictive enough to rule ou t pathogenicity. In summary, the clinical significance of this variant cannot be determined with certainty at this time; however, based upon the computational d ata, we would lean towards a more likely benign role. -
